How to Make a Bearing Drill Rack

The fantasies of a good home master are characterized by a wide variety of works. They contain parts such as bodies of revolution, which are made on lathes for wood and metal. However, to acquire ownership of such a machine will be an expensive undertaking for the family budget. The manufacture of turning equipment using a drill will expand the capabilities of the master.


If on a manual snap, which is often used in work, the handle breaks. Or, for example, your task is to make chess pieces as a gift. These and other similar works can be performed using a lathe made on the basis of an electric drill. On do-it-yourself equipment, the handle will turn out to be as convenient as possible, and the chess pieces original.


The traditional version of the lathe includes the following main components: electric drive, bed (base), front headstock, tailstock, caliper. An electric drill is used as an energy source (electric drive) on a home-made lathe.


Designed to accommodate all other nodes. She perceives the whole load when working for herself. Therefore, the bed must have a margin of safety. The design minimally deforms when performing work, ensuring the accuracy of manufacturing parts.

The bed is highlighted in red

In the classic version of the lathe, the bed is a site technologically difficult to manufacture. Its surface, interfaced with other assembly units included in the lathe, is performed with high precision requirements. In the process of its processing, special high-precision equipment is used.

The accuracy of the machine is largely dependent on the quality of the bed. Therefore, this is an expensive part. In a home-made version, the requirements for the final product are much simpler, the bed (base) can be made from any available materials that do not require expensive processing.

Front headstock

In the front headstock of the lathe is an electric motor with a gearbox and a control unit. Its functions include transmission of rotation, as well as basing the workpiece for the purpose of processing. Another name for the headstock is spindle, because the main part of this assembly is the spindle. This is a multi-stage shaft with a bore inside, rotating in precision adjustable bearings.

From the side of the working area there is a flange to which a three-jaw self-centering cartridge is attached. Through the holes in the shaft, various clamping devices, for example, a collet, are installed. The workpiece is fastened in a home-made machine using a drill chuck of an electric drill, that is, it has significant limitations.

The control unit of a conventional lathe allows you to choose almost any option for machining a part according to the technological process. In a home-made version, the function of the headstock is performed by an electric drill along with the base on which it is attached. Therefore, the choice of workpiece processing mode is limited by the functionality of the power tool.


To create the necessary rigidity during processing, the workpiece is fixed on both sides. This is especially important for long parts. Therefore, the back is located against the front headstock. In the case of the tailstock is a stubborn or rotating center, which serves to preload the workpiece. A cutting tool such as drills, countersinks, reamers can be installed in the tailstock.


The support of the lathe provides the supply of the tool to the processing zone. Typically, the tool is mounted in a special tool (tool holder), which is placed on the caliper. The kinematic diagram of the caliper allows it to move both in the longitudinal direction and in the transverse relative to the axis of the spindle. To obtain conical surfaces, the tool can be installed at an angle.

The working tool of lathes is set in motion both manually and with the help of mechanical devices. On home-made lathes, the supply of the tool to the cutting zone occurs mainly with the help of manual physical force.

Step-by-step instruction

There are many options for making a do-it-yourself lathe from a drill. However, in principle they are not much different from each other. In fact, this is an electric drill, adapted to work in conjunction with the structural elements of a lathe.

  • When choosing the design of the bed, it is necessary to consider the possibility of placing it on the desktop (workbench) of the home master. It can be attached to it using clamps or threaded connections, depending on the magnitude of the load during processing. The bed allows you to easily move the lathe from the drill with all the nodes installed on it in case of a change in location as necessary.

The dimensions of the bed must be selected in accordance with the size of the workpieces. If there are corners of 40×40 mm or a square pipe of such a section, welding a bed of this metal will be a good option. It is imperative to provide for a groove along which the tailstock and the handler move. In the absence of a corner and square pipes, it is possible to make a bed of wooden blocks.

  • Depending on the model of the selected electric drill, a stand is developed for it. A structure is made of three plywood plates knocked together with each other and a base with a lodgement under the drill body. The stand is attached to the bed, while the supporting part of the drill is pressed against the tool tray using a clamp. Also, you can try to fix the drill on the bed with an iron clamp. Both options are presented in the pictures below. The method of attaching a drill is not limited to only these options. You can experiment and invent your own. It is important to attach the drill so that it rests on the bed without movements and backlash during operation.

  • For the tailstock we assemble a corner from two wooden bars. It is attached through the groove to the bed. In one of the bars a hole is made for a furniture loop with an internal thread. A tip with a tip sharpened under the cone is twisted into it. The entire assembly is clamped with a nut located on the side of the working area. This location prevents the tailstock assembly from unwinding.

Important: The axis of the tip must match the axis of rotation of the drill chuck. This will reduce the runout of the workpiece during processing and make the processing of workpieces better.

  • As a replacement caliper, on a lathe made of a drill, a handicraft is used. It moves freely along the guide groove of the bed, providing a minimum clearance between the handrail support and the rotating workpiece. This is due to the fact that the tool on the support of the handrail is held manually. The distance between the workpiece and the support should not increase the moment of force, reducing the physical efforts of the machinist. The mount provides a secure fit in the working position.

The correct layout on the bed of all these nodes will allow turning of the workpieces. If you develop additional equipment for a home-made machine from a drill, then from processing simple cylindrical bodies of revolution, you can move on to more complex ones. A set of diverse clamping cones, flanges and mandrels will expand the range of workpieces.

The material used for processing is a well-dried wood. You can work and try to work with metal, but for this you need good skill and experience. Some “soft” metals (copper, aluminum), when used in the construction of a powerful drill, can undergo shaping.

In the private sector, various cutting tools are sharpened using grinding wheels. The use of felt and polishing wheels makes the work surface clean and smooth.

The priority in using lathes from a drill belongs to the processing of wood blanks. The maximum effect is achieved in obtaining curly surfaces. A tool that is made from worn files, with the help of human thought and physical strength, is able to create unusual art forms.

When using the machine, do not forget to observe basic safety precautions!
